DEEP-WELL PUMP.

Application led March 27, 1922. Serial No. 547,200.

To aZZ whom it may concern.' y

Be it known that I, GEORGE L. FULLER, a citizen of the United States, residing at Sisquoc, in the county of Santa Barbara and State of California, have invented new and useful Improvements in Deep-fell Pumps, of which the following is a specification.

This invention relates to deep well pumps for use in oil wells or other wells, and contemplates an improvement on the device disclosed in my Patent 1,416,277, May 16, 1922. At the present time it is customary in deep well pumps to provide what is known as a standing valve which may be withdrawn or seated through the medium of what is known as a Garbutt rod aociated with the plunger and with the 4standing v-alve. TheA Garbutt rod is so formed and so inter-connected with the plunger and the standing valve as to permit the plunger to reciprocate within the limits of the pump stroke without unseating the packing of the standing valve from its seat; The present invention, however, does away with the Garbutt rod 4and has for one of its objects the seating and unseating of the standing val've, and whereby the plunger and the standing valve may be independent 0f each other during `the working stroke of the plunger. A further object of the invention resides in the automa-tic unlocking of the standing valve from the plunger.

The invention has for further objects ,the provision of a pum of the general character stated which will, be superior in point of relative simplicity and inexpensiveness of construction, combined with positiveness and effectiveness of operation, compactness in form, economy in power and freedom from frictional loss and wear and tear, and facility in repair, and which will be generally superior in eicency and serviceability.

With the above and other objects in view, the invention consists in the novel and uscful provision, construction, formation, combination, association and inter-relation of parts, members and features, all as hereinafter described, shown in the drawing, and finally pointed out in cl-aims.

In the drawing: Figure 1 is a fragmentary, vertical sec` tional view of a pump constructed and organized in accordance with the invention;

y Figure 2 is a top plan view showing one of the members of the present invention, associated with the standing valve;

Figures 3 and 4 Iare fragments of the me'nber associated with the standing valve; 1 an Figure 5 is a plan view of theplunger nut adapted to cooperate at times with the member illustrated in Figures 1 to 4 inclu s1ve. f

Corresponding parts in all the figures are designated by the ame reference characters.

Referring to th drawing, A designates the barrel member/ of a pump, B the plunger, C and D members which may interengage for the purpose of withdrawing the standing valve E; all of which members may cooperate inthe practice of one embodiment of the invention. The'members C and D may be 'termed interlocking or gripping members, inasmuch as they cooperate at times to 'withdraw the standing valvel E from its seat. The member C may include the usual form of plunger nut having ascrew-threaded engagement as at 1, with the plunger B. The plunger nut Cyas is customary, is annular in form, and in the adapt-ation shown, is provided with two inwardly directed and diametrically opposed studs 2 and 3.

The standing valve E is annular in form and includes the usual crown member 4, a

bea-ring seat 5 adapted to receive a ball or y other member 6, the crown member 4 normally confining the ball member to maintain 4the same in position. The standing valve E likewise includes an annular body member 7 carrying packing rings 8 so as to hold the same in close engagement with an endpiece 9` said end-piece being coupled to the barrel A as by means of a ring member 10. As the pump is operated oil 0r other liquid is drawn into the space above the standing valve upon the 11p-stroke of the plunger A, rising above the Working valve upon the next down stroke of the plunger, and thereafter being elevated with a column of liquid above it to produce flow at the mouth of the well.

At times it is necessary to remove the standing valve E from the endlpiece'9 and in order to do this the members C and D interlock or grip each other in la manner to be described. The member D includes for reception in a threaded opening in the 2 and 3 of the plunger nut C so that the standing valve may be removed from the end-piece 9 if desired, but if the plunger nut is in engagement with the gripping portion 11 a seating of the standing valve will automatically disengage the gripping members so that the plunger and its plunger nut may be withdrawn, leaving the standing valve seated. The member D is adapted to be received within the plunger nut C and the. member D is formed with grooved portions 13 and 14, which grooved portions outline and form two peripheral members a and Z) built upon and integrally formed with a core member c., The members a and b are located on opposite sides of the core member o and the grooves or channels 13 and 14 are so formed as to,V cause the memt bers a and b to terminate in pointed portions 15, which portions are not in alignment with the center line of the core c, and for reasons yto be explained. The grooves`13'and 14 may best be described b v describing how they form the members a and b and as the same. includes two vertical portions 16 and 17l with a lateral portion 18, said lateral portion being undercut on an incline, as

shown at 19 and 20. The lateral portionl 18 Vand the Vertical portion 17 are joined by a curve 21 which terminates at a point beyond the point of junction 22 where the inclined'or undercut portions 19 and' 20 meet.- The triangular pointed portions 15 of the members a and Z) are provided with inclined or beveled edges 23, which preferably are beveled downwardly toward the grooves 13 and 14. It is of course to be understood in referring to the grooves and the particular form thereof, that the Ywall ,portions are referred to; that is to say, the walls formed by the grooves in the making "of the core andthe members a and b.

Assuming the position of the plunger nut C as shown in Figure 1, a dropping of the plunger and the plunger nut would cause the studs Qand 3 to engage the beveled walls 23 of the members ka ,and b, and as the apexes of said triangular portions are ott' the center line of thecore, the plunger nut is given a twist 'so as to direct the studs within the grooves13, 14 and 16. l, This is diagrammatically illustrated in Figure 4, the pointed lines in said ligure illustrating components of force. A twisting or turning of the plunger will exert a pressure in the direction of the horizontal arrow and the of the members aand b, as shown in Figure' 3. A dropping of the plunger -with the plunger nut will cause the studs 2 and 3 .to follow the wallsof the grooves 17, 21 and 18 turning the nut C and the plunger automatically. plunger might cause the lugs 2 and 3 to engage or liss the undercut wall 19 and in either vcase the lugs would be directed `to the channel 16 and the plunger nut would be released from the member D. It will thus be seen that means have been providedavhere by the plunger nut is automatically disengaged from the member D upon a lowering thereof.

It is obvious that a device of this character does away with the necessity of having any connection between the plunger and the standing valve. Consequently the plunger will reciprocate within given limits or may exceed those limits, or even contact with the standing valve and yet,` unless the proper turn is given the plunger nut the standing va'lve will not be removed. Furthermore, the standing valve after being seated is automatically released from the plunger by allowing the plunger to rotate slightly and if it is desired to again remove the standing valve it is only necessary to lower the plunger so as to cause the plunger nut to engage the standing valve and a rotation of the plunger will cause `the stud members connected with the plunger nut to ride within the grooves, as has been stated, and lock with the members a and to remove the standing valve.

It is manifest that the invention will produce a great saving in time, incident to repair of the pump parts, ,and will enhance the length ot' life of the working parts of the pump. Furthermore, the partlcular con-l struction shown with its center core c lends great strength in the structure. The various features incident to practicing the invention are simple and inexpensive in construction, and not liable to require frequent or troublesome replacement.

In standard practice the standing valve is removed or pulled out when the rods and plunger are removed, and alloil within the tubing flows back to its level. In the present invention the plunger, working valve and rods may be removed, but the standing ltion, formation and association of parts,

members and features, in the practice of the invention, and in the adaptation of the same to varying conditions of use and service, without departing from the truel spirit of the invention.
